“I don't like to share my personal life... it wouldn't be personal if I shared it.”

Simplified Meaning:

When someone says that they don't like to share their personal life because it wouldn't be personal if they did, they are saying that certain things are meant to be private and not told to everyone. Personal experiences, feelings, and thoughts are special and private. If you tell everyone those things, it makes them less special and less private. For example, think about a diary where you write your thoughts and secrets. If you showed your diary to everyone, those secrets wouldn't be special or private anymore. Keeping some things to yourself means those things stay important and just for you. In your own life, if there's something that means a lot to you or makes you feel vulnerable, you don't have to tell everyone about it. It's okay to keep some things to yourself. This can make you feel safer and more comfortable about your own experiences. Sharing too much with everyone can sometimes lead to problems, just like sharing your password with strangers could lead to trouble. So, it's good to think about what you want to keep private and what you feel okay sharing with others.
